99% Tabular Alumina Manufactured by ISO9001 2008 Certified Henan with Corundum

Henan manufacturer Tabular corundum high quality 99% tabular alumina

Tabular corundum is a kind of pure sintered corundum that does not add any additives such as MgO, B2O3 and so on. 

Tabular corundum has a coarse and well-developed α-Al2O3 crystal structure. The content of Al2O3 is more than 99.3%. Crystal-like structure with small pores and many closed pores. The porosity is roughly the same as that of fused corundum.

Rabular corundum has high purity, good volume stability, and minimal re-fire shrinkage. The refractory or castable used for the production of refractory materials or castables has good properties after high temperature treatment Thermal shock stability and flexural strength.

The main properties of tabular corundum:

1. Refractoriness ≥1800℃, and its melting point is as high as 2050℃.
2. It has a coarse and well-developed a-Al2O3 crystal structure, which greatly improves the creep resistance.
3. Plate-like crystal structure, small open pores, low porosity, low water absorption; more closed pores inside, good thermal shock resistance and peeling resistance performance. To
4. Since no additives are added in the production process, the purity is high, the volume stability is good, and the reheating shrinkage is very small.

Technical indicators of sintered tabular corundum:

General size of tabular corundum:

Gain: 5-8mm 3-5mm 1-3mm 0.5-1mm

Fine powder: 325#

Tabular corundum usage:

Tabular corundum can be used as the main component in aluminum-carbon, aluminum-magnesium-carbon, magnesia-aluminum-carbon, magnesia spinel, and aluminum-chromium refractory bricks, or it can be introduced into high-alumina refractory bricks as a component of enriched alumina. Shaped refractories can be widely used in steel, casting, ceramics and other industries, and the application in the steel industry almost covers the entire process of ironmaking and steelmaking.

The well-known tabular corundum is used to make abrasives. Due to the superhard properties of emery ceramics, it can be prepared into various grinding wheels, emery cloths, sandpapers and various abrasives, which are widely used in the machining industry.

Tabular corundum material also has self-lubricity and low friction coefficient, which is about half of that of cemented carbide. Its thermal shock resistance and high elastic modulus are used in some special places, such as high-power The performance of the laser mirror is better than that of copper, due to its low density, good rigidity and small deformation. As a new type of material, it has been applied to battery anode materials, new ceramics, solar energy industry, seals, automobiles and other industries.
